I think the people who designed this puma encounter guide failed to realise two important facts: (1) People tend to read pictures as a temporal sequence. (2) Not everybody can read English.
If I ignore the text, my interpretation of this sign would be as follows:
- Move backwards, holding out your hand to the puma (to make it follow you?).
- Then hold up your hands and scream in terror.
- Now get your kids and feed them to the puma.
